Carpets are a common feature in most homes.

They make a room feel cozy while adding texture and warmth.

However, dirt, dust, and allergens thrive in carpets.

Regular vacuuming removes surface debris, but only deep cleaning can eliminate bacteria and nasty stains.

So, how often should you clean your carpets?

Hubert Miles, Certified Master Inspector and owner ofPatriot Home Inspectionsin South Carolina, shares why.

“Carpets should be professionally cleaned every 12 to 18 months,” says Miles.

Deep cleaning helps remove dirt and grime from carpet fibers.

Which factors determine how often to deep clean?

Various factors impact the frequency of cleaning carpets.

Pets:Furry four-legged friends tend to track in dirt and germs from outside.

Even indoor pets are prone to accidents.

Pets also shake off dander and hair that can build up over time.

So, consider avacuum designed for pets.

It will have enhanced features to tackle hair and shedding.

Allergies:Unclean carpets canworsen allergic conditions, asthma, or hay fever.

Vacuums with HEPA filters work well to keep allergens at bay.

But frequent dry vacuuming can make allergens go airborne, making reactions worse before they get better.

Try running an indoor air filter regularly and moving smoking to outdoor areas not exposed to windows and doors.

Piling, Fibers, & Color: Materials alone may make frequent cleaning necessary.

Light-colored carpets quickly reveal dirt.

In contrast, dark-colored carpets can hide stains.

Also, the kind of carpet fibers can determine how much dust it attracts.

When should you replace carpet?

Miles says carpets can last 5 to 15 years with professional cleaning and proper care.

Failing toclean carpets regularlycan lead to a buildup of bacteria, dirt, and germs.

You will likely smell the damage even if you don’t see it.

Worse still, you’ll feel it.

Weekly dry vacuuming with a robot vacuum can keep carpet maintenance to a minimum.
